It's 6*length^2, or 216 cm^2.

If 6 cm is the length of the side, the surface of one side is 6 x 6 = 36 cm squared. And the total surface is 36 x 6 = 216 cm squared. This is because the cube has 6 sides.
Interestingly enough, the volume of this cube is 216 cm cubed. Because 6 x 6 x 6 (or 6 cubed) also equals 216.

a cube has 6 exposed surfaces, each in the shape of a square. the area of a square with edge length of 6cm is 36 cm². a cube made up of squares having 36 cm² area would have a surface area of 216 cm³.

The surface area of a cube is the added area of each face. The area of one face is 6 * 6 =36.
There are 6 faces on a cube, so you multiply 36 and 6 ao get a total of 216 sq. cm. Area is always in units squared

A cube has 6 faces.Each face is like a square with all sides of equal length(6 cm).
area of square = length of side^2.
so total surface area of a cube = 6*(length^2)
= 6*(6^2)=216 cm sq

The formula to find surface area for a cube is
2(lw)+2(hw)+2(lh)
2(36)+2(36)=2(36)=
72+72+72=
216 cm

Because all sides of a cube are equal, one face is equal to 6x6 (edge x edge), which is equal to 36. A cube also has six faces, so you multiply the surface area of one face by the number of faces (6). 36x6=216. This is your answer.

how many surfaces does the cube have?
6
What is the surface area of one of the sides?
6 x 6 = 36
So if you add up the surface area of each side you have:
Total Surface Area= 36 + 36 + 36 + 36 + 36 + 36 = 216.

6cm x 6cm x 6 sides
should yeild 216 cm^2

surface= 2lw + 2lh + 2 wh
=2 (6*6) + 2 (6*6) + 2(6*6)
= 2(36) + 2(36) + 2(36)
= 72 + 72 + 72
=216
